Exchange 2010 on a 2003 domain
A user can connect using Outlook 2010 to his mailbox on an in-house machine, but when he vpn's in from his home computer he gets this error:
The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete the action
pinging the mail server works
the mail server name, both simple and full, is in the hosts file
he claims there is no firewall running on his home computer and previously, when his mailbox was on the old Exchange 2003 server, he could connect using outlook with no problem
Thanks for any help on this.
